Maybe you guys are right. There's a lot of it in that container which was dry, and its a lot more like axle grease than oil slick. Ill try the dry experiment and see what happens.
Maybe the load of pulling the van around shook up a lot of silt in the motor or heater core.
The radiator was about 6 months old when I did the swap the first time, so its pretty clean
